High-level theory is the view that high-level properties?the property of being a dog, being a tiger, being an apple, being a pair of lips, etc.?can be represented in perceptual experience. Low-level theory denies this and claims that high-level properties are only represented at the level of perceptual judgment and are products of cognitive interpretation of low-level sensory information (color, shape, illumination). This paper discusses previous attempts to establish high-level theory, their weaknesses, and an argument for high-level theory that does not have these weaknesses.
